CLOCK-DIAL FOR PROGRAM-CLOCKS.

Specification of Letters Patent.

Patented July 29, 1913.

Application led December 22, 1911. Serial No. 667,309.

To all whom t may concern Be it known that I, AUGUs'rUs IV. SOUTH, citizen of the United States, residing at Red Oak, in the county of Montgomery and State of Iowa, havey invented certain new and useful Improvements in Clock Dials for Program-Clocks, of which the following is a specification.

tion with a. circular dial having' radial gradnations, either one or twov bulletin boards divided-,by transverse lines into a series of transverse spaces, the lines being connected to the radial graduations of the clock dial by'guide lines whereby cach space upon the bulletin'board or boards is connected to a corresponding time graduation so that the 'eye may be led either from any certain space upon the bulletin board to `the appropriate time indication upon the dial vof the clock or from any time indication to the correspondving space upon the board, thus providing means whereby any event indicated on a bulletin board or program may be correlated with any particular time mark on the clock dial or vice versa.

A further object is to provide in Iconnection with the circular ,dial having radial graduations, a column or a pair of parallel columns, preferably vertically arranged,v

each column divided into horizontal spaces I having time notations and each space connected by radial lines with the corresponding time Vmark on the circulardial. There is thus provided a means whereby the position of the hand or pointer on the circular dial may be readily noted and the exact time read, even though the central dial be relatively small, or even though the central dial be unprovided with any time notations.

A furtherobject is to combine the vertically arrangeddial denoting spaces with the bulletin boards above referred to so that the time for any particular event may be read in connection with the statement of the event itself.

My invention is illustrated in the accompanying drawing wherein the figure isa face view of a clock face showing the central dial, laterally disposed bulletins, and an intermediate dial. Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

2 designates a circular dial oft any suitable material and which maybe th-e ordinary dial of a clock, watch or other timepiece. This dial Iis provided with radial graduations or time marks indicating hours, h alf hours, quarter hours and fractions thereof. The subdividing of each hour space may be carried to' any degreerequired but preferably there is an indicating mark or graduation for each tive minutes. The marks indicating the hours will naturally be the most conspicuous, the marks indicating the half hours the next in degree, thequar- Iter hour marks of less prominence, andthe 'tive minute` marks leasty prominent of all.

In order that these marks may be easily read, the margin of the dial 2 is preferably provided with a series of three or more concentric circles, these circles being designatedl 3. The hour marks extend from the edge of the dial 2 inward, intersecting all of the circles 3 and extending beyond these circlesl toward the center of the dial. The half hour marks extend from the edge of the dial through the last circle but not so far toward the centerv of the dial as the hour marks. The quarter of an hour marks extend from the edge of the dial to the third circle but not beyond the same. The mark indicating the first ve minutes after or before a half hour mark extends from the vedge of the dial to the first circle 3 but not beyond the same, while the mark indicating the first five minutes before or after the half hour extends to but not though the second circle 3. It will `thus be Seen that the time marks grow longer from each half hour mark to each quarter hour mark and then grow shorter from the quarter hour mark to the next adjacent hour mark.

The clock mechanism may be of any suitablel character and 'preferably the clock is provided with only one hand, 4, this being 'the ordinary hour hand of the clock and making a complete revolution around the dial either in twelve or twenty-'four hours, according to the style of clock, it being bvioiis thatmy invention may be equally as well applied to a 21 hour 'clock as to a 12 hour clock. Preferably the hour marks `are numbered in the usual manner so that the hour may be read by means of the hand 4 alone.

Arranged preferably on opposite sides of the dial are the programs or bulletin boards 5 and 6, the board 5 corresponding, we will say, tol that portion of the dial from l2 oclock noon or midnight to 6 a. In. or 6 p. n1., and the board 6 corresponding to that portion of the 4dial from 6 a. m. to 12 noon or 6 p. m. to midnight. In case the clock is a 24C hour clock, each bulletin 'board would correspond to twelve hours. We will assume, however, that it is a 12 hour clock and that one bulletin corresponds to the hours from six in the morning to twelve noon, and the other from twelve noon to six in the afternoon.

Each bulletin or program is divided by vhorizontal lines 7 into a vertically arranged series of spaces 8, each space corresponding to a particular instant of time. Preferably these spaces 8 correspond to each 15 minute graduation mark though a closer subdivision might be used if desired, this subdividing of the bulletin board into 15 minute spaces being merelyfor illustration. At the end of each space Ais-preferably disposed a triangular mark 9 forming a bracket, the apex 'of the bracket pointing inward or toward the central clock dial 2. These brackets or trianglesv 9 are preferably placed upon what may be termed an intermediate dial 10v which surrounds the central dial 2' and extends from the central dial to the bulletin boards on each side. Extending across this intermediate dial are the radially arranged lead or guide lines 11, each extending from one of the` graduation marks on the central dial to the apex of one of the triangular ybrackets 9. It is obvious that these guide lines 9 will be spaced apart and that advertising matter, announcements or other indicia ma7 be placed within these spaces. The eye 1s thus led by means of the guide lines from any particular'time mark upon the clock to the appropriate space on a bulletin or program.

Preferably and in order that not only the time may be easily read but the events stated on the program may be correlated with the proper time indicia, the bulletin is also pro- 'vided with a column 12 immediately adjacent to the triangular brackets 9 wherein the time notation for each space 8 is set down. Thus the clock may be read Aby observing the positionv of the hour hand and following the line 11 leading from the adjacent grad.l

uation to the time notations in column 12 of one or the other of the bulletin boards. At

' the same time the events stated in the bullietin boards will be displayed in connection with stated time marks and thus the time for the occurrence of these events may be easily seen at' any moment. It will, of course, be obvious that the right! hand bulletin will be read downward and the left hand bulletin upward in accordance with the movement of the clock hand.

It is perfectly plain that for special purposes, such as places for entertainment, the clock may be made coextensive with any length of program or time-table so that one complete circuit of the hand or pointer will be made during the time of performance. Thus for theaters or other-places of amusement, the hand of the clock will make one complete circuit in` one, two or more hours, depending upon the length of the performance, while for railroad stations and the like, one complete circuit of the hand 4 may be made every 24 hours, the clock train being regulated accordingly.

My combination clock and program or bulletin board is particularly useful for schools, theaters, railway stations, and in all situations where a series of eventsl is scheduled to take place each at its proper time. It may be furthermore pointed outthat it is hardly any ditiicult-y for even an ignorant person to read the time correctly on a clock having a dial as described, provided with -tlie vertical columns 12 on each sidc of the main clock and with the. lead lines 11 extending from the time graduations of the clock to the time notations in the columns 12. Even a child can note the lposition of the hour hand, follow the' lead line extending from it vand read the figures in the columns 12.

What I claim is:

1. A timepiece including a face having a central circular dial provided with radi' ating time graduations produced from the center of the dial, parallel vertically disposed bulletins arranged-one on each side of the dial and laterally spaced therefrom along their whole extent, each bulletin being longer than the diameter of the dial and extending above and below thexsanie, veach bulletin having a series of defined horizontal indicia receiving spaces of equal size and corresponding to equal divisions of time` and diverging lines extending across ythe lface of thc timepiece, each extending parallel vertically disposed bulletins located one on each side of the dial and spaced therefrom, each bulletin being longer than the diameter ofthe dial and extending above and below the same, each bulletin having a series of defined horizontal indicia receiving spaces of equal size and corr sponding to equal intervals of time, and dlverging lines extending acrossl the face of the timepiece, each line extending from one of the time graduations on the dial to a corresponding space on the bulletin,'th'e said lines defining indicia receiving s aces, each of the indicia receiving spaces o the bulletin being provided with4 a time indicating character corresponding to the time indicating graduations with which said space is onnected by the corresponding diverging lne. v

3. A timepiece including a face having a central circular dial provided with radiating time graduations produced from the center of the dial, parallel vertically disf posed bulletins arranged one on each side of the dial and laterally spaced therefrom along their whole extent, each bulletin being longer than the diameter of the dial and extending above and below the same, each bulletin having a series of defined. horizontal indicia receiving spaces of equal size and corresponding to equal division of time, and diverging linesA extending across one face of the-timepiece, each extending from one of the time graduations on the dial to a corresponding space upon the bulletin, said diverging lines defining indicia receiving spaces, each bulletin on its inside margin having a vertical line or lines dening vertical columns, the intersection .of each horizontal space and such vertical columns being provided with a. time designating character corresponding in value to the time graduation on the central timepiece with which said space is connected.

In testimony whereof I aliix my signature in presence of' two witnesses.4 l
